APC AP13045MR Propeller for Electric Multirotor 13x4.5MR  [AP13045MR]

APC AP13045MR Blade Brief

The APC AP13045MR is a multirotor prop specifically intended for electric RC craft. The 13x4.5MR code identifies its diameter and pitch, helping pilots pair the blade with appropriate motor and ESC setups on small to medium multirotors. This brief covers fitment tips, simple install checks, and how the prop influences handling and tuning.

Fit guidance: the MR profile denotes multirotor usage and aligns with APC's range of multirotor props. Before mounting, confirm rotation orientation and make sure the mounting nut or adapter secures the hub without play. Never force a mismatched hub size; check against existing props or the motor adapter first.

Mounting checklist: inspect the blade for defects, install in the correct rotation, hand tighten the retaining hardware, then perform a low-throttle spin test for clearance and vibrational issues. If vibration occurs, remove and inspect the blade and hub; replace any warped or cracked components. Regular inspections help keep motors and ESCs within normal operating loads.

Tuning guidance: a 13x4.5 blade tends to offer a middle ground between thrust and efficiency; altering diameter or pitch will change thrust and flight feel. Make incremental changes and evaluate results at low throttle before full flight.
